How would I know if my Bach 4G mouthpiece is a Remington Shank (88H) or not?

I ask because it fits well into my large bore 0.547 inch Blessing B88 (similar to Conn 88H I think) but it "wobbles" in my Bach large bore tenor. Would that suggest that this MPC is a Remington shank? I picked it up used many decades ago from a box of loose mouthpieces.

The reason I am confused is because I have a Bach 1/2 G mouthpiece--bought new decades ago-- that does seem to fit securely into both trombones--B88 and the Bach--and so I'm wondering how the 1/2 G fits well in both horns but the 4G does not? Maybe the 4G is just worn?

What info from me would help you help me? Thanks in advance! :good:

The Remington shanks are longer than the standard Bach shanks, in addition to being a bit thicker. Wobbling isn't actually a way to determine this - sometimes something is a little bit out of round. The Blessing would not have the same receiver as an old Elkhart Conn 88H. Many old Conns accept a standard Bach mouthpiece very well, except that it goes further into the receiver. That type of fit often changes the response of the instrument, but that also doesn't mean that it won't play fairly well, and maybe even do some things better.

If your 4G has an outside that appears to be the same as the 1.5G, then it's definitely not a Remington shank, and something is just a little bit out of round on either the mouthpiece shank or inside the receiver. I've had a few very good (sometimes expensive custom models) that wobbled a little bit in one horn or another. Usually turning the mouthpiece slightly as it is inserted into the horn can help that.

Also, a Bach mouthpiece with a Remington shank will have an R under the size.

Remington mouthpieces have a lot less taper in the shank.

My Bach 6 1/2 AL in Remington is actually marked 88H

I think that I've seen a Mt. Vernon version that was unmarked, but the 5G that I owned also had 88H stamped on the shank.

I have a 1961 88H. A Bach mouthpiece does wobble a little in the receiver.

The Remington that comes with it is a true fit. I bought an Elliott mouthpiece with a Conn shank - perfect fit.

Hello and thank you. My 4G shank is the same length as my 1 1/2 G. It also lacks a 88H stamp, too. So that clears it up that my 4G is NOT a Remington shank. And thanks to CalgaryTbone on clarification on the Blessing. I always wondered that! On the 4G it does seem like my 4G is a bit out of round so that probably explains the wobble. Makes sense now that I think it. I learned something today.
